- i claim. (ci. sii-21) The present invention relates to a furconditioning machine, and although it is broadly applicable to nachinesfor processing of furs, skins and other materials having a proteinaceousor nitrogenous pile material, it has' a particular application to therenovating or rejuvenating of fur clothing and particularly fur coats.

lt is among the objects of the present invention to provide a furprocessing, and particularlyfur coat processing, machine which wmeffectively rejuvenate and refurbish fur without either damage. to thefur or lining and witn assurance that this operation will be carried outspeedily, with a of manual labor.

Another object is to provide a fur processing I nachine which may beutilized for the refurbishing or rejuvenating fur coats, which. willfeed the coat into the iromng machine without any danger of ripping ortearing or weakening of the lining and with assurance that the fur willbe given renewed luster.

Still further objects and advantages will appear in the more detaileddescription set forth below, it being understood, however, that thismore detailed description is given by way of illustrationy andeirplanation only and not by way of limitation, since various changestherein may be made by those skilled in the art without departing fromthe scope and spirit of the present invention.

ln accomplishing the above objects it has been found most suitable,according to one embodiment of the present invention, to provide a highspeed, heavy metal iron ing roller in readily fixed position, having onthe exterior face thereof a plurality of spiral grooves havingrelatively sharp-edge, replaceablev blades oril thedeep .side of thegrooves.

These grooves serve to comb and separate and renew the individual fibersof the fur.

Desirably, this roller is provided with an internal, cylmdrical,electrical resistance element which is fed by an alternating, two-phaseor three-phase circuit and it is also provided with thermostatic controlwhich will regulate such temperature within narrow, desired limits so asnot to damage the fur and at the same time assure maximum effectivetreatment thereof.

While the ironing roller is in fixed position and at an elevated point,upon the structure, the support for the fur garment to be processed iselevated and lowered by means of a bracket or carrier structure providedwith rollers which in turn carry a traveling belt, preferably of felt orcanvas material. Although the belt may be permitted to turn freely uponrollers, it is desirably driven by means of a motor at a slower speedthan the rotating roller.

There are provided manual means for elevating and lowering the rotatingbelt so as to apply the fur garment to the rapidly rotating roller froma table upon which the fur garment is supported.

Desirably a hood is provided which will take up all loose fibers anddust from the roller, and associated with this hood is a suction fan.

With the foregoing and other objects in view the invention consists ofthe novel construction, combination and arrangement of parts ashereinafter more specifically described, and illustrated in theaccompaning drawings, wherein is shown an embodiment of the invention,but it is to be understood that changes, variations and modificationscan be resorted to which fall within the scope of the claims hereuntoappended.

ln the drawings wherein like reference characters denote correspondingparts throughout the several views:

Fig. 1 is a front elevational view of the fur conditioning machine,partly in section to more clearly show the 'line s-s of Fig. 2.

Fig. 4 is a side view partly in section of a detail of the construction,showing the variable belt pulley arrangement.

Fig. 5 is a side elevational view partly in section and upon an enlargedscale as compared to Fig. 2, showing the adjustable pulley in adifferent position from that shown in Fig. 4.

Fig. 6 is a vertical side sectional view, similar to Fig. 3, of analternative cradle operating construction.

Fig. 7 is a front elevational view, partly in section and similar toFig. 1,- of said construction of Fig. 6 showing the parts in slightlydifferent position.

Referring to Figs. l to 3, there is shown the ironing roller A supportedupon the frame structure B. The ironing roller A has. an interior heaterconstruction C and it is provided with an exhaust and blower arrangementD driven by the motor E, which also drives the ironing roller A.

The carrier belt arrangement F is driven through a flexible shaft G fromthe variable speed unit H.

The machine frame B has a base 10, a lower front cover 11, the sidecovers 12 and the back cover 13. These covers may be held in position bymeans of the screws 14.

Upon the front of the casing is positioned the table 15 mounted by thebrackets 16 upon the front wall 11.

The table 15 has a centrally located cut-out as indicated at 17 throughwhich projects the moving belt arrangement F.

The ironing roller A is enclosed in a hood I which has a top wall 18with the oblique forward flange 19 and the oblique rear flange 20.'I'lie forward ange has a depending lip 21 which will terminate justabove the rotating roller A.

The hood J has the funnel member 22, which at its reduced center 23opens into the casing 24 of the blowei' D. 'Ihe blower D has a vanemember 25 which rotates on the shaft 26 to the rear of the ironingroller A.

The stream of air which is drawn into the hood I and which is exhaustedthrough the opening 27, picks up all dirt and dust which is dischargedinto the dust collector D.

The ironing roller has the spiral grooves 35 (see Figs. 1, 2 and 3),which are faced with the sharp, vertically grooved steel blades 36.

These blades are turned in the direction 37 against the fur, which isalso moving in the direction 38, being carried by the belt F.

The roller A has the end plates 39 with the hubs 40 which enclose theheater shell C and through which lpasses the central shaft 41. The shaft41 has a triple pulley 42 thereon, driven by the three belts 43.

On the shaft 41 are three contact rings 44 for contacting triple phasecurrent to the heater element C, and at the other side there is providedthe two contact rings 45 leading to an automatic electrical temperaturecontrol (not shown).

The shaft 41 is provided with end bearings 46 supported by the anges 47on the end walls 48. The end walls 48 are part of the enclosure 49 oneach side of the main ironing roller A.

It will be noted that the enclosures 49 are separated from the hood I bythe partition having openings at 51 for the hubs 40.

The exhaust blower D has a pulley 60 upon the shaft 26. The pulley 60 isdriven by the belt 61 from the pulley 62 on the motor shaft 63.

The motor E which drives the shaft 63 has a body 64 mounted by thesupport 65. The motor supporting the base 66 is pivoted on the shaft 68and the position of the base 66 will be determined by the length of thebelt 6l. The base 66 may slope in either direction re1- ative to thepivot shaft 68 and it may be either oblique or horizontal.

The bracket 66 has a support ear or lug 67 which may 3 be pivoted on theshaft 68. The shaft 68 bears in the bracket 69 on the ange 70, turninginwardly from the lower rear wall portion 11.

The support base 66 for the motor E has the upturned or right angle rearsection 72 upon which is adjustably mounted` the variable pulley memberH. p

The mounting on the block 73 is adjustable by means of the screws 74 andthe handle 75. The handle 75 may be turned to elevate or lower thevariable pulley I-I.v

As best shown in Figs. 4 and 5, the variable pulley H has a body 90, acentral shaft 91 and the two at cone members 92 and 93. 9Between the atcone members 92 and 93 is the belt The spring enclosed in the housing 90tends to pull the members 92 and 93 together to the position in Fig. 4while the belt 94 tends to separate the anges 92 and 93 to the positionas shown in Fig. 5.

As a result, the deeper the belt 94 pulls itself between the anges 92and 93, the lower the speed ratio will be.

As shown, the belt 94 is driven from the pulley 95 on the motor shaft63.

The drive goes through the shaft 96 of the adjustable pulley devicc Hand then passes through the reduction box 97 (see Fig. 2). Then itpasses through the exible cable G to the shaft 98 of the roller 99carrying the felt belt 100 of the belt arrangement F.

The felt belt 100 is carried by the lowermost pulley or roller 99 andthe outside pulley 101 as well as the inside pulley 102 and 103.

The rollers 102 and 103 are positioned so as to present an oblique faceto the roller A when the carrier F is elevated.
